Coleoptera — When I show how how high Lamellicorns rank, add, & their affections seem highly developed

We have seen that Lethrus live by pairs & ♀ encourages the ♂ in battles. In another & very different genus Ateuchus the pair seem deeply attached even after pairing, for as is well known that female deposits her eggs in a pellet of dung & female then backwards into a burrow & during this operation the male stands by. (Journal of Travel. p. 135 quote).

Descent 1: 376: "The two sexes of another lamellicorn beetle, the Ateuchus cicatricosus live in pairs, and seem much attached to each other; the male excites the female to roll the balls of dung in which the ova are deposited; and if she is removed, he becomes much agitated. If the male is removed, the female ceases all work, and as M. Brulerie66 believes, would remain on the spot until she died."
